小题3:____ Before I came to England I had thought that fish and chips were eaten every day. That’s quite wrong! I get rather annoyed now when I hear all the foolish words about typical English food.

I had expected to see “London fog”. Do you remember our texts about it? We had no idea that most of this “thick fog” disappeared many years ago when people stopped using coal in their homes. But the idea to speak about weather was very helpful. 小题4:___ On the other hand, habits are different.
